There's not a bad one on your itinerary. Don't miss the private island, Princess Cays is bliss.
I wouldn't want to miss any of them actually...
The other resorts - the quietest/smallest one is Grand Turk, there is a Margaritaville right at the port, but not much else close, or keep walking to the L and go to Jack's Shack for lunch. You will need to take an excursion to see much of the island, either via the cruise ship or independently booked or a taxi.The town is not much at all...... It's a tropical island, so snorkeling, swimming,sailing, beach activity are the attractions
Definitely dont stay on board when you go to St Maarten or St Thomas.
You have a couple of days at sea on your itinerary to relax.........
It all looks GOOD to me!

Thanks Emdia, looks like we may have to get off at all the stops, but I suppose you are right we do have a couple of days at sea and the embarkation day to enjoy the ship's facilities.
